Description

Technical Field

[0001] This utility model relates to the technical field of PI protective film cutting, and in particular to a PI protective film forming device. Background Technology

[0002] PI film, or polyimide film, is the world's best-performing thin-film insulating material. It is made by polycondensation of pyromellitic dianhydride and diaminodiphenyl ether in a highly polar solvent, followed by casting and imidization.

[0003] Chinese patent CN221186763U discloses a PI protective film forming device, including a base. A housing is fixedly connected to the top of the base. A carrier is fixedly installed at the center of the top of the base. A through groove is formed on the surface of the carrier. An electric telescopic rod is fixedly connected to the center of the top of the base. A square plate is fixedly connected to the output end of the electric telescopic rod. A sliding block is fixedly connected to the top of the square plate corresponding to the through groove. The outer wall of the sliding block engages with the inside of the through groove. The top of the sliding block is flush with the top of the carrier. Electric telescopic rods are fixedly connected to both sides of the carrier at the top of the base. Air guide pipes are fixedly connected to the output ends of the two electric telescopic rods. The inclusion of air guide pipes facilitates thorough removal and cleaning of scrap material during cutting, improving the cutting efficiency of protective film scrap material.

[0004] The aforementioned patent requires fixing the PI protective film before cutting it, and the cutting of the protective film cannot be carried out continuously. Furthermore, existing devices that can continuously cut the protective film are prone to breakage when transporting the cut protective film, as the joints are weak after cutting. Therefore, improvements are still needed. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems existing in the above-mentioned protective film forming device, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide a protective film forming device to solve the problem that "the protective film needs to be fixed first, and the cutting of the protective film cannot be carried out continuously".

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a protective film forming device, comprising:

[0029] Reference Figure 1 -4. This utility model provides a PI protective film forming device, comprising:

[0030] The conveying unit 100 includes a base 101, a top plate 102 fixedly mounted on the top of the base 101, a protective film 103 slidably mounted on the top of the top plate 102, a side plate 104 fixedly mounted on the top of the base 101, a gear 105 and a gear 106 rotatably mounted on one side of the side plate 104, the two gears meshing with each other and rotating in opposite directions, the outer wall of gear 105 meshing with gear 106, a conveying roller 107 fixedly mounted on one side of both gear 105 and gear 106, the two conveying rollers 107 rotating in opposite directions, an auxiliary component 108 provided inside the top plate 102, a motor 109 fixedly mounted on the top of the base 101, the motor 109 providing power for the conveying of the device, a pulley 1 fixedly mounted on one side of the output shaft of the motor 109 and one side of the conveying roller 107, the outer walls of the two pulleys 1 together being fitted with a belt 1, the pulleys preventing the belt from slipping or misaligning;

[0031] The cutting unit 200 includes a U-shaped plate 201, which is fixedly installed on the top of the base 101. An electric telescopic rod 202 is fixedly installed at the bottom of the U-shaped plate 201, and a cutting blade 203 is fixedly installed at the bottom of the electric telescopic rod 202. A spring telescopic rod 204 is fixedly installed on the top of the base 101 corresponding to the position of the cutting blade 203. A receiving box 205 is fixedly installed on the top of the spring telescopic rod 204, and the cutting protective film is received through the receiving box 205.

[0032] The auxiliary component 108 includes a conveyor wheel 108a, which is rotatably mounted inside the top plate 102. A chain wheel 108b is fixedly mounted on one side of the conveyor wheel 108a, and a chain 108c is sleeved on the outer wall of the chain wheel 108b. A rotating rod 108d is fixedly mounted on one side of the chain wheel 108b, penetrating the top plate 102. Pulleys 102 are fixedly mounted on one side of both the gear 106 and the rotating rod 108d, and belts 1082 are sleeved on the outer walls of both pulleys 106. Multiple conveyor wheels 108a are used to fix both sides of the protective film 103 and assist in transmission, preventing the cut protective film 103 from being torn during transport.

[0033] Furthermore, there are two gears, 105 and 106. A pulley is fixedly mounted on one side of each gear 105, and a belt is fitted onto the outer wall of both pulleys. A conveyor roller 107 is fixedly mounted on one side of each gear 105 and 106. The four conveyor rollers 107 are respectively attached to the upper and lower sides of the top plate 102. The gears 105 and 106 cause the two conveyor rollers 107 to rotate in opposite directions, facilitating the conveying of the protective film 103.

[0034] Furthermore, there are multiple conveyor wheels 108a, each with a chain wheel 108b fixedly mounted on one side. The chain wheels 108b are interconnected in pairs via chains 108c. A rotating rod 108d is fixedly mounted on one side of the first rotating rod 108d. It connects to gear 106 at one side, simultaneously driving the multiple conveyor wheels 108a to rotate.

[0035] Furthermore, a support block is fixedly installed at the bottom of the top plate 102, and the support block is fixedly installed on the top of the base 101. The side of the conveying roller 107 away from the gear 105 is rotatably installed on the side plate 104. The support block stabilizes the position of the top plate 102, while the side plate 104 stabilizes the rotation of the conveying roller 107 and prevents the conveying roller 107 from tilting.

[0036] Furthermore, the top plate 102 has a rectangular through hole that mates with the cutting blade 203, and the receiving box 205 is slidably inserted into the rectangular through hole of the cutting blade 203. The protective film 103 is cut by the interaction between the cutting blade 203 and the rectangular through hole of the top plate 102.

[0037] During use, motor 109 first drives one of the conveyor rollers 107 to rotate, and gear 105 and gear 2 106 drive the other conveyor roller 107 to rotate. The two oppositely rotating conveyor rollers 107 convey the protective film 103 forward. At the same time, the rotating rod 108d driven by gear 2 106 through belt drives rotates synchronously. The rotation of the rotating rod 108d drives the first chain wheel 108b and the conveyor wheel 108a to rotate. Multiple chain wheels 108b are mutually driven by chain 108c, so that all the conveyor wheels 108a rotate at the same time for auxiliary transmission.

[0038] When the protective film 103 reaches the bottom of the cutting blade 203, the electric telescopic rod 202 presses the cutting blade 203 down, causing the cutting blade 203 to cut the protective film 103 and insert it into the rectangular through hole of the top plate 102. The cut protective film 103 falls into the receiving box 205, thus completing the cutting.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
